Soliciting to do look up for $$$$$ !!!!!

I was emailed privately by a Thomas P Barber saying his company would do a census look up for Hancock, IL for a small fee.He said he could look up at the Mesa Family History Center or do look ups at his office.Is this the norm?Is he allowed to use the Family History Center to do look ups for a fee?Could someone let me know.I think it is inappropriate that he contacted me using my personal email instead of posting it to my query in this forum.
